Definitions

  • the present invention relates to a production line for producing series of identical articles.
  • Such production lines are used today in almost all branches of industry, especially in the electronics and automotive industries, but also in watchmaking.
  • the basic principle is always similar: a workpiece to be machined is transported on a conveyor belt from one processing station to the next, and a production step is carried out at each processing station.
  • a component can be mounted on the workpiece, an electronic component can be soldered onto a circuit board, a test or a measurement can be carried out, or the workpiece can be processed in any other way.
  • the present invention is therefore an object of the invention to provide a production line that can be retrofitted as quickly and inexpensively.
  • the modular production line comprises at least one base frame on which a conveyor belt for transporting workpiece carriers runs.
  • a conveyor belt for transporting workpiece carriers runs.
  • On the conveyor belt can of course be transported instead of workpiece carriers, on each of which a workpiece to be machined, even workpieces.
  • workpieces to be processed are located on workpiece carriers.
  • the modular production line comprises a multiplicity of production units which can be fastened on the base frame.
  • Each production unit has at least one functional element and at least one control unit.
  • the functional element may be, for example, a robot which mounts an additional component, which lacquered or coated the workpiece, performs a test or a measurement or performs other assembly or processing steps.
  • the term "functional element", in the context of the present invention, includes not only robots, but any tools or processing units, feeder units, etc. that can be used in production lines.
  • Each production unit also comprises on the one hand means for conveying a workpiece carrier from the conveyor belt of the conveyor Base frame to the functional element and on the other hand means for conveying a workpiece carrier from the functional element back to the conveyor belt.
  • the base frame with the conveyor belt is independent of the production units, and therefore does not have to be disassembled when converting the production line. Also, the conveyor belt does not need to be stopped because regardless of the presence of production units workpiece carriers can be transported with workpieces lying thereon. For converting the production line so only the required manufacturing units must be used. The individual manufacturing units are independent of each other, so that each can be replaced or implemented individually without affecting the rest of the production line. Since each production unit is equipped with a control unit and with means for conveying a workpiece carrier from the conveyor belt to the functional element and vice versa, no central calculation is needed to control the production line, which would have to be reprogrammed consuming in the case of retrofitting.
  • the means for conveying a workpiece carrier from the conveyor belt to the functional element comprise a first conveyor belt
  • the means for conveying a workpiece carrier from the functional element to the conveyor belt comprise a second conveyor belt.
  • the means for conveying a workpiece carrier from and to the functional element can each comprise a slider arranged above the respective conveyor belt and movable in its conveying direction.
  • a workpiece carrier can be pushed by the conveyor belt onto the first conveyor belt, on which it then moves to the functional element becomes.
  • After processing by the functional element of the workpiece carrier is transported by the second conveyor belt back in the direction of the conveyor belt and finally pushed by the second slide back onto the conveyor belt.
  • the workpiece carriers are preferably not stopped, but the slides make it possible to redirect them out of the movement on the conveyor belt in the direction of the functional element of the production unit.
  • the slides can be controlled so that there is an approximately sinusoidal velocity curve of the slider.
  • the workpiece carrier is thus gradually accelerated to a maximum speed, and decelerated again before the transfer to the conveyor belt or the conveyor belt. In this way, the time required to move the workpiece carrier is minimized without exposing the workpiece on the workpiece carrier to the forces encountered in the high accelerations and jerky movements.
  • the conveyor belt is approximately twice as wide as the two conveyor belts, which are for transport from the conveyor belt to the Function element or vice versa serve.
  • the width of a conveyor belt corresponds at least to the width of a workpiece carrier, and a conveyor belt with twice the width can then be operated in two lanes.
  • a two-lane operation of the conveyor belt allows a faster and more efficient distribution of the workpiece carrier on the production units, so that in the same period of time more workpieces can pass through the production line than in a single-lane operation.
  • conveyor belts whose width is a multiple of the width of a workpiece carrier, and which can be operated accordingly multi-track.
  • the production units can all be arranged on one side of the conveyor belt, so that one of the tracks acts as a turning lane, while a lane facing away from the production units serves as a fast lane.
  • the production units may each comprise a further slide, which is arranged in the transport direction of the conveyor belt before the means for conveying a workpiece carrier from the conveyor belt to the functional element, that is, for example, in front of a first conveyor belt with associated slide.
  • This additional slider can move a lying on the remote from the production unit track ("fast lane") of the conveyor belt workpiece carrier on the production unit facing track ("turn lane") of the conveyor belt.
  • this workpiece carrier can then be pushed by a in the transport direction of the conveyor belt further back slide, which is part of the means for conveying a workpiece carrier from the conveyor belt to the functional element, on a conveyor belt, which then brings him to the functional element.
  • another be provided additional slide which serves to move a workpiece carrier, which is not to be discharged to the relevant manufacturing unit, from the production unit facing track ("turning lane") of the conveyor belt on the production unit remote track ("fast lane").
  • the base frame preferably has a drive for driving the conveyor belt.
  • a simple drive motor that drives the conveyor belt at a constant speed is sufficient.
  • the base frame can thus do without a control, whereby a conversion of the production line is facilitated.
  • the conveyor belt is preferably provided with a removable cover to protect the workpiece carriers and the parts lying thereon from dust.
  • a hood made of transparent Plexiglas can be used. This is preferably in comparison to the environment under an overpressure, so that a particularly efficient dust protection is achieved.
  • On the cover dividers for dividing the conveyor belt may be mounted in a plurality of tracks and lateral boundary webs, so that the conveyor belt itself is not fixed to a specific arrangement of manufacturing units or to a certain dimension of workpiece carriers.
  • the base frame may comprise a table, which is preferably made of granite and has a rectangular table top. The conveyor belt can then be attached to a longitudinal side of the table and extend parallel to this longitudinal side.
  • the production units can be fastened next to each other in a simple manner, but it can also be set up a manual workstation.
  • a production line will comprise a plurality of such base frames, which are constructed next to one another such that the respective conveyor belts belonging to a base frame form a continuous transport path.
  • At least two, but preferably three centering elements are provided on an underside of the production units, which cooperate with complementary centering on a surface of the base frame.
  • the balls are in correctly aligned manufacturing unit in the hemispherical recesses on the surface of the base frame.
  • the rotatably mounted balls on the underside of the production units not only facilitate the correct alignment of the production units on the surface of the base frame, but they also allow rolling the production unit on the surface of the base frame until the balls in the recesses provided for this purpose to come to rest.
  • two or three centering elements for each one manufacturing station can be provided on the surface of the base frame and a grid-like arrangement of centering. This gives greater flexibility and can correctly align and assemble production units in different masses and with centering elements provided at different locations.
  • At least one of the production units comprises a feed device for feeding parts.
  • a feed device for feeding parts For example, screws or components to be assembled can be supplied to the functional element.
  • several production units may include such feeders.
  • Such feeders so-called “feeders”, are available on the market in various designs.
  • feeders are available on the market in various designs.
  • different types of feeders are selected and installed on the manufacturing unit.
  • the production units are each provided with at least one reading unit, which is connected to the control unit of the respective production unit.
  • the reading unit may be, for example, an RFID reading head. It is possible to attach RFID transponders to the workpiece carriers or the workpieces themselves, in which data relating to production is stored. Thus, for example, an order of processing steps to be performed or an order in which the production units are to be controlled are stored in the RFID transponder.
  • the reading unit may then read the processing step to be performed next, and pass this information to the control unit. This then determines whether it is the processing step, which is performed by the relevant production unit. If this is the case, it orders the corresponding workpiece carrier to be conveyed by means provided for this purpose from the conveyor belt to the functional element of the production unit.
  • the manufacturing units may have a writing unit which can modify data stored in a memory associated with a workpiece carrier. If RFID transponders are fastened to the workpiece carriers or the workpieces, they can have a writable memory in which, as described above, an order of processing steps is stored. Before the workpiece carrier is conveyed from a production unit back onto the conveyor belt, the writing unit connected to the control unit can note in the memory of this workpiece carrier that the corresponding processing step has been carried out. The subsequent intended processing step then advances in the memory to the place of the next processing step to be carried out.
  • the invention also relates to a method of operating a modular production line as described above.
  • workpiece carriers provided with a writable memory are transported on a conveyor belt, wherein an order of assembly steps to be carried out is stored in the memory.
  • a value stored in this memory which represents the next assembly step to be carried out, is read out.
  • This value is then compared with a value representing the assembly step that can be carried out by the relevant production unit. If the two values match, the workpiece carrier is conveyed from the conveyor belt to the functional element of the production unit.
  • the functional element then performs a processing step, for example a mounting step, a measurement or a test.
  • the data stored in the memory of the workpiece carrier is modified, and the workpiece carrier is conveyed from the functional element back to the conveyor belt.
  • the reading and writing units connected to a control unit, no central control unit is required to control the entire production line, but with the aid of the data stored in the RFID transponders, each production unit itself ensures that the workpiece carriers are at the right time to that belonging to the one Functional element to be transported.
  • Another advantage of the inventive production line is, moreover, that the modular arrangement in combination with a very compact design of the manufacturing units leads to both the workpiece carrier and all other moving parts, such as For example, a mounting robot, only relatively short distances must cover.
  • Fig. 1 shows a base frame 10, which is part of a modular production line according to the present invention.
  • the base frame 10 consists essentially of a granite table 12 with a rectangular table top 12a and two L-shaped side parts 12b, the on height-adjustable feet 12c rest.
  • On one of the longitudinal sides of the table 12 an endlessly circulating conveyor belt 14 is mounted, which runs parallel to this above the table top 12a.
  • the conveyor belt 14 is at a first deflection point 15 ', which is approximately at the level of in Fig. 1 lying on the right-hand end of the table, guided over a rotatably mounted, driven guide roller.
  • This deflection point 15 ' can also be on the outside of the table top, so that when two tables next to each other, a gap between the table tops.
  • a motor is provided which is not visible in the figures, and the conveyor belt 14 drives at a constant speed in a transport direction T.
  • the conveyor belt 14 is guided over a thin guide shaft, which is firmly clamped laterally outside the conveyor belt 14 in a frame 11, and on which a plurality of spaced slide bushings are rotatably arranged.
  • the deflection shaft is supported by intervening between the bushes supporting webs or support pins.
  • Such a deflection device is in the German patent application of 14 August 2006 with the file number 10 2006 038 185.8 IWB Industrietechnik GmbH, to which reference is hereby made. Due to the small radius of the supported deflection shaft and small parts can be transferred from another conveyor belt to the conveyor belt 14 without falling into a space between the deflection points of the two conveyor belts.
  • Fig. 1 By way of example, two workpiece carriers 50 are shown, which essentially have the shape of plates with a frame surrounding a rectangular base.
  • any other workpiece carriers can be used, and it is also possible to transport workpieces to be machined without such a carrier directly on the conveyor belt.
  • the conveyor belt 14 is operated in two lanes. Each of the two tracks 14a, 14b is just wide enough for a workpiece carrier 50. On the outer sides of the conveyor belt 14, limiting webs 18, 18 'extending in the transport direction T serve as guides for the workpiece carriers 50.
  • the two tracks 14a, 14b are of separating webs 16 separated, which run parallel to the lateral boundary webs 18, 18 'and of bridges 19, 19' are held.

How to get in Fig. 4 sees, is located at the correctly positioned production unit 20, a portion of the body 31 below the conveyor belt 14. For holding the production unit additional mechanical fastening means may be provided. Before the production line is put into operation, furthermore, the connections 40, 42 on the base frame 10 are connected via suitable hoses and cables to corresponding connections on the production unit 20.
